Filed a case on 16th December - 4 weeks after an item was ordered and 2 weeks after it should have been delivered. 

Case moved to 2nd stage of "We are reviewing the information" on 19th December. It is "stuck" at this point.
The estimated case resolution date keeps increasing by a couple of days at a time and is now at 14th Jan. 
Seller has not responded to this or any contact. 

Online chat do not deal with this as it was via PayPal Credit.
Customer services do not deal with it and all updates will be via the resolution centre.
There is no email address to try. 

I seem to be in limbo with this open dispute that has an ever-increasing end date and no way to talk to anyone about why ? 

Any ideas folks ? 

PS. Item has still not arrived.
